Abstract

The hydrothermal extraction was carried out in a semi-batch extractor at a temperature of 160 °C, pressure of 7 MPa, and a water flow rate of 1 mL/min. Electrospraying was conducted at various voltages of 12, 14, and 16 kV, various distances between tip and collector of 6, 8 and 10 cm, precursor solution flow rate of 0.05 mL/h, and PVP concentrations of 6 and 8%. Particles obtained from electrospraying process were analyzed by SEM, FTIR, and spectrophotometer. The antioxidant efficiency (AE) of the particles was also examined. Based on the results, the morphology of particles was spherical with diameter less than 3 µm. The highest value of AE was 0.1058 min^-1, which indicated that Gracilaria sp extract in the particles produced by electrospraying has good antioxidant activity. In the FTIR analysis, carrageenan and flavonoids were contained in the particles. The result indicated that hydrothermal extraction followed by electrospraying process could be one alternative process for obtaining the best phytochemical particles.
